Application fiIed'JanuaryB, 1920. Serial No. 349,260.

To all wizom it may concern:

Be it known that I, LOUIS F. I LIllE, a

citizen of the United States, residing at Walla Wallayinthe county of -Walla Wa la and State of Washington, have invented certain newand useful Improvements in Building-Blocks, of which the following is a specification.

This intention relates to improvements in building blocks and has for its object to proride a strtu-ture that 71s snnple m construetion and of ample strength in all its parts.

A further object is to provide a structure that may be firmly bound together on all its sides.

A. further object is'to provide a structure wierein the courses of the building structure may be bound togetherwithlugs.

.33 further object is to provide a hollow structure containing cavities thati extend throughout the vertical height of the block in. manner to aiforda continuous cavity 'or air space throughout the vertical the builded structure.

further objectis to provide a structure having reinforcement fabricated therein in a manner to provide a lock centrally posiheight of tioned in the outer perimeter .(or nearly so) of the block, and on one side thereof, and which does not requlre particular care n construction to embed as the bedding Wlll be automatically carried on as the binding mortar is applied.

lVith these and other objects in view reference is had to the accompanying drawings in which Figure 1 is a perspective view of a portion of a wall constructed of the blocks and resting on V a foundation Fig. 2 is a perspective View ofa lower portion of the block;' I

Fig. 3 shows a door framewhich may be used in constructional work of certain classes and which is a modified form of my block; and

Fig. 4 is a sectional elevation of the blocks.

Having reference to the drawings like numerals refer to like parts throughout and the numeral 1 refers to the foundation which maybe of any approved design that will cross arms 0f the T extended upward to form lugs 6.

specification ofLettersIatent. at t d jigg 1921;

The partition divides the hollowinto two cavities which are continuous throughout the vertical height of the block; the upper ends ofsthe cavities are partlyclosed by-the lugs (5, the lugs being positionedto register iwith the lower end ofthe cavity in the 1 superposed f'block. By this means I provide a lockingarrangement between'two courses which at the same time provides a continuous air passage throughout the vertica height of the builded structure. a j

In the block is provided a groove 7 upper surface of the block andis extended longitudinally throughout one half-thewhich? -lS posit oned in the outer portion of the length of the block where it terminates in a vertical hole Swhieh is positioned vertically in the block to receive the succeeding comple'mental reinforcing member 9' which will now be explained. 1

This reinforcing member consists of'a bar, or other reinforcing means, and is provided at both ends with looking hooks 10 or other fastening means by which two blocks of a course may be locked together. One

halfof this member 9 is embedded or fabri rated in the block as shown at 11-, with one of thehooks bent about the vertical hole 8,

and the other half extendsin a mannerto seat in a groove 7 of the adjoining blockwith the hook positioned to seat in the vertical hole 8, of the adjoining block, surrounded by the first mentioned hook of the adjoining member 9, the vertical hole,locking hook and groove being alined for this I purpose.

In construction the foundation is pre pared and a block laid thereon with the usual binding-mortar, the succeeding adjoining block islthen laid with the reinforc ing member 9 seated in the groove ,7 with the hook 10 within the locking hook and vertical hole 8; a second course may now, be started in a similar manner, W1th tl16 usual broken oints, as shown n Fig. 1, by

lacin the mortar on the lower course 1n the usual manner and resting the block thereon. I the act 'of placing the mortar on the blocks of the lower course will completely cover the exposed portion of the reinforcing me'mg her without additional labor and the pres- It will now be readily seen that Thus with the courses held l rigidly in place by the lugs there can be no lateral play; with the lugs positioned only partly over the cavities a continuous vertical air space is maintained; with the reinforcing designed to present a solid unjointed material at the place of joiningof two adjacent blocks; with the lock of said reinforcing members centrally located in the blocks, the structure must be held rigidly together and the whole finally completed as one solid lllil SS.

Having thus described my invention, 1 claim- 1. In a building block, a hollow structure having a continuous cavity throughout its vertical height and having lugs positioned in said cavity to register with the cavity of the succeeding superposed block and in a manner to provide a continuous cavity throughout the vertical height of the builded structure,a locking reinforcing means in said block with the loclcthereof positioned intermediate the ends of said block and with continuous unbroken reinforcement between two adjoining blocks of a course. i

2. In abui-lding blo'ckfa hollow structure comprised of outer walls and containing a partition having a T shaped form in section, the ends of the cross arms of the T being extended to form lugs, said "partition forming a plurality of cavities in said structure, said lugs being positioned over and partly closing the said cavities in a manner to register with the cavity of the succeeding superposed block and tojprovide a continu ous cavity throughout the vertical height of the builded structure, a locking reinforcing means consisting of a groove positioned in the outer portion of the upper surface oi the said'block and extending longitudinally throughout onehalf the length thereof and terminating in a vertical hole, and a reinforcing member, one half of which is enibeddedin said block with the other half extending to rest in a correspondlng groove of an ad om1ng block, said member carrying locking hooks on both ends thereof with one of said hooks positioned about said vertical hole, said vertical hole, locking hook and groove being alined to receive the complemental extended portion of the reinforcing member of the adjoining block.

In testimony whereof I affix my signature LOUIS F.'KLINE.
